A broadcasting device of the present disclosure includes: a reception unit which receives reception interference information notified from the reception device; a setting unit which sets a frequency of a notch to be provided in a transmission signal on the basis of the reception interference information that has been received; a modulation unit which provides the notch in accordance with the set frequency of the notch while at the same time generates a modulated signal by modulating information to be transmitted; and a send-out unit which sends out the modulated signal as the transmission signal. For example, the present disclosure can be applied to a broadcasting system which transmits a broadcasting signal conforming to DVB-C2 via a CATV network or a CATV Internet system (DOCSIS), a physical layer of which conforms to the DVB-C2 standard.
